Economic results of organic meadow farms were assessed in this paper. Gross margin was at a medium or low level there. It decreased when calculated per ha of croplands and increased when calculated per capita with the increasing farm area. In the greater part of farms, gross margin showed an increasing trend in both calculations. Possibilities of further investment and development showed c. 66% of studied farms in 2009 and 69% in 2008. Gross margin in zł per ha of croplands was correlated with the farmers' age; the largest was obtained by the oldest and experienced farmers while the smallest - by the youngest farmers at the age of 25 to 35 years. The largest gross margin was obtained by the youngest farmers when calculated per capita. Employment was lower in their farms which increased physical and economic labour efficiency. Subsidies were an important factor affecting the economic results. On average they constituted 44.30% of gross margin in 2009 and ranged from 31.9% to 59.64% depending on the farm size. The study confirmed a working hypothesis that ecological food production is possible in organic meadow farms providing a specific level of subsidies. The most beneficial economic results were obtained in farms oriented to the production of highly efficient dairy cows and young beef cattle. These farms have the greatest capacity for ecological production without subsidies. The largest gross margin, calculated both per capita and per ha, was obtained in farms breeding more than 25 cows. Milk efficiency also increased with the herd size and was the greatest at the number of cows >25.
